5ml High Pressure PTFE Digestion Vessel for Geological Mineral Analysis Corrosion Resistant Polytetrafluoroethylene TFM Digestion Inner Liner

Product Overview

This high-pressure digestion vessel represents the pinnacle of sample preparation technology for trace element analysis. Specifically engineered to handle the most aggressive acidic reagents, the unit provides an isolated environment for the complete mineralization of complex matrices. By utilizing premium-grade fluoropolymer materials, the system ensures that volatile elements are retained while organic and inorganic components are fully decomposed under controlled thermal and pressure conditions. This equipment is an essential component for laboratories requiring the highest levels of purity and recovery in their analytical workflows.

Primarily utilized in geological, environmental, and metallurgical research, this system excels in the dissolution of refractory minerals, soil matrices, and industrial ores. The high-performance liner is designed to integrate seamlessly into high-pressure digestion assemblies, facilitating the rapid breakdown of samples using concentrated acids like nitric, hydrochloric, and hydrofluoric acid. Its robust construction makes it a preferred choice for geochemistry departments and commercial testing facilities where precision and durability are non-negotiable requirements for day-to-day operations.

Engineered for reliability under demanding conditions, the vessel features exceptional thermal stability and chemical inertness. The choice of materials minimizes the risk of cross-contamination and reagent leaching, which is critical for Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and other sensitive detection methods. With its focus on structural integrity and chemical resistance, the unit provides researchers with the confidence that their sample integrity is maintained from the initial weighing through to the final dilution, even when subjected to extreme high-pressure digestion cycles.

Key Features

• Superior Chemical Inertness: Constructed from premium PTFE or modified TFM, this vessel resists attack from all common laboratory acids, including aqua regia and hydrofluoric acid, ensuring the vessel does not introduce impurities into the sample.
• High-Pressure Structural Integrity: The reinforced wall design allows the unit to operate safely in high-pressure environments, enabling the digestion of tough mineral matrices that would remain unaffected in open-vessel systems.
• Low Trace Metal Background: The ultra-pure material selection ensures that the vessel has an extremely low elemental background, which is a critical requirement for high-sensitivity trace and ultra-trace metal analysis.
• Enhanced Thermal Stability: Capable of maintaining structural and chemical properties across a wide temperature range, the unit facilitates high-temperature digestion processes without deformation or degradation of the material.
• Precision CNC Machining: Each vessel is manufactured via advanced CNC fabrication, ensuring tight tolerances for sealing surfaces, which prevents the loss of volatile target elements during the mineralization process.
• Customizable Material Options: Users can specify the use of TFM (modified PTFE) for applications requiring lower permeation rates and improved recovery of specific volatile elements.
• Smooth Internal Surface Finish: The high-quality machining process results in a non-porous, smooth internal wall that prevents sample adhesion and simplifies the cleaning and decontamination procedures.
• Bespoke Design Flexibility: Every aspect of the vessel can be tailored to meet specific laboratory requirements, from volume adjustments to specific cap configurations for specialized digestion systems.
• Advanced Sealing Mechanism: The interface between the liner and the cap is engineered to maintain a hermetic seal under elevated pressure, ensuring consistent results and operator safety.
• Durability and Longevity: Designed for repeated high-cycle use, the robust fluoropolymer construction offers a long service life, providing a superior return on investment compared to standard consumable liners.
